After putting some homemade pollen substitute patties, I thought they ate it up. After an inspection on one hive it was completely gone, but when I looked in a different hive, it was still there with crumbs scattered everywhere. It seems they are attracted to it since I mixed some syrup with it, but the crumbs look like it is the yeast that they seperated from it.
Here is the mix:
3 parts soy flour
1 part yeast ( I couldn't find brewers so I used bread yeast)
1 part dry milk
Mixed it with as much 1/1 syrup with hbh, until it was like playdough consisity.
Rolled it into patties and put it in freezer.
Maybe wrong/bad ingredient? Maybe not enough water? Maybe I should have let the yeast work a little before putting in freezer?
I also weighed the end result and found that I can buy them cheaper than making them.
